How is synovitis formed

summary

Grandfather suffering from synovitis, mainly because of gout secondary, serious when joint function is greatly limited, mobility, need to pay attention to is different etiology, solution is not the same. Let's see how synovitis is formed.

How is synovitis formed

First: infection. Bursitis can be caused by injury, some of which are direct violence injury, some of which are excessive joint flexion, extension, abduction, external rotation and so on. After repeated, long-term, continuous friction and compression, the bursa strain leads to inflammation, and the bursa can be thickened by wear, such as kneeling workers' prepatellar bursitis, thin elderly women's ischial tuberosity bursitis after sitting for a long time, and shoes are too tight In addition, the pathogenic bacteria carried by the infected focus can cause suppurative bursitis.

Second: gout. Gout is a metabolic disease caused by increased uric acid synthesis due to abnormal purine metabolism. When the renal function is abnormal, the decrease of uric acid clearance rate of the kidney will also lead to the rise of uric acid level, and the uric acid in the plasma will reach saturation, resulting in the deposition of monosodium urate crystals in the tissue around the distal joint which is relatively lack of blood vessels. The appearance of this crystal can lead to acute inflammatory synovitis of single joint or multiple joints.

Third: tumor. Local invasion and distant metastasis are the most important characteristics of malignant tumors, and are the main causes of death. Tumors are formed by the proliferation of a transformed cell.

matters needing attention

Synovitis is generally caused by frequent excessive activity, long-term friction and compression of joints. Timely treatment should be carried out after the disease, and the amount of activity should be reduced to prevent the disease from aggravating.
